I just rebooted, no major problems except... my middle-clicking ability is gone! Any ideas what might have caused this and how I can get this back. It is a travesty

Scroll wheel still works, interstingly enough. Thoughts?

No idea what the problem is, but I'm having it too. No response to middle button whatsoever. 'xev' doesn't report anything when I hit it.

It's a PS/2 Logitech Trackman Marble FX, fwiw.

It seems clicking with both mouse buttons works, as though Emulate3Buttons was on (it's not). xev registers the left button as 1, the right button as 3, and both as 2. the middle button, as you said, doesn't get picked up at all (it's a wheel on mine, and up & down gets correctly registered as 4 & 5). I've got a PS/2 Logitech Wheel Mouse. I tried turning on ChordMiddle to see if that'd do anything, but no dice.

Same problem here. I switched to a pure udev system around the same time as this kernel, and thought it was related to that (as udev changed my mouse from /dev/mouse to /dev/psaux, forcing XF86Config changes). I hadn't thought about it being kernel related. As the above poster, it is a PS/2 Logitech Wheel Mouse.

I installed 2.6.6-r3-love1 yesterday which I believe is vanilla-based and it is horribly unresponsive when doing big emerges (eg cryto) , to the point where I just walk off and do something else until it's done.

I have been impressed by previous love sources where I can lauch three major emerges , play music and still work through postings on gentoo.org with almost unaffected mouse responce.
